Water filter with stainless steel filter how to carry out backwash

With the development of science and technology, our filtering equipment is becoming more and more perfect. Today, let us know how to use stainless steel filter element to carry out backwashing. It is usually installed in the inlet of the equipment, or installed in the pressure relief valve, pressure relief valve, water level valve, they are usually used to remove some impurities in the medium to protect the normal use of valves and equipment. When the liquid flows into the stainless steel filter element of the normal size filter screen that we use, the impurities are intercepted, and the clean filtrate is discharged by the filter outlet, when it needs to be cleaned, as long as the removable stainless steel filter out, re-loading after treatment can be, therefore, the use and maintenance is extremely convenient.

So such a filter equipment, its filter element is how? Its filter is the use of a relatively high-quality filter made from the screen, through the detection of pressure difference, the filter will be cleaned regularly. When the impurities in the filter accumulate on the surface of the filter causing the pressure difference between the inlet and outlet to increase to the set value, or when the timer reaches the preset time, the electric control box sends out a signal to drive the backwash mechanism. If the suction hole of the backwash suction cup and the inlet of the filter element are just opposite, open the drain valve, at this time, the system pressure drainage, suction cup and the filter element inside a relative pressure less than the water pressure of the filter element outside a negative pressure zone, the part of pure circulating water is forced to flow from the outside of the filter to the inside of the filter, and the impurity particles adsorbed on the inner wall of the filter can flow into the disc with the water and be discharged from the discharge valve. There is also a certain attention to the design of the filter, when you make a special design of the filter, then the internal filter produced by the spray effect is different, any impurities will be washed away from the smooth inner wall. When we set the filter inlet and outlet pressure to return to normal or the preset time is up, the whole process, material flow, backwash water consumption is small, to achieve continuous, automated production.
